JOHN F. WORRALL, OF OOjNSOOKET, RHODE ISLAND.

RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters'Patent No. 257,198, dated May 2,1882.

Application filed April 8, 1880. (Modch) To all whom it may concern Beit known that I, JOHN F. WoRnALL, of \Voonsoeket, in the county ofProvidence and State of lthode Island, have invented a new and usefulImprovement in Ring Spinning Machines; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying tlrawi'ngs,tbrmi1]ga part of thisspecification.

In the ordinary ring-spinning machines the operator determines when thedoffing of the cops or bobbins shall take place, and he moves thetraversing rail back to the position it must occupy in starting thewinding of fresh cops or bobbins.

The object of this invention is to automatically reverse the onward orbuilding movement of the traversing rail at the moment when the copsorbobbins have been completed and return it rapidly to the position forstart ing fresh cops or bobbins.

To this end my invention consists in the combination, with thewinding-drum, of the mechanism for reciprocating and giving an onward orbuilding movement to the traversing rail, of a reversing mechanismautomatically connected to and disconnected from the windingdrum for thepurpose of reversing the motion of said drum the moment the cops orbobbins have been filled, and return therebythe traversing rail to theposition for starting fresh cops or bobbins.

It further consists of combinations arising from certain arran gementsof the mechanical de-. vices hereinafter particularly described, whichcombinations will be set forth in the claims at the close of thisspecification.

In order that my invention may be clearly understood, I have illustratedin the annexed drawings and will proceed to describe the best formthereof known to me at the date of the filing of the application forthis patent. I

toshowfor illustrating the application of my reversing-mechanism. Fig. 1is a side elevation, in detail, of the mechanism for actuating"the-traversin grail, the weighted quadrant bellcrank being omitted andrepresented by a weight. Fig. 2 is a perspective view of the principalparts shown in Fig. l I Figs. 3, 4, and 5 are illustrations of details,drawn on a larger scale than. the other figures.

The same letters of reference indicate similar parts in all the figures.

My invention can be applied to any kind of ring-spinning machines,whether used for spinning warp or filling, and whether it operates witha reciprocating or traversing ring-rail or with a stationary ring-rail.I have illustrated it as applied to a ring-spinning machine operatingwitha traversing ring-rail and arranged to spin filling laid in conicallayers on the cops or bobbins.

The stem or rod A of the ring-rail A rests upon the horizontal arm ofthe bell-crank B, fixed to a shaft, 13, which is provided with an armcarrying the weight B for overbalancing the ring-rail, so that thebell-crank constantly tends to lift the ring-rail. The upright arm ofthe bell-crank is constructed with a quadrant or segment, B to which oneend of the chain g is connected. The chain is conducted over a sheave,13, down to the horizontallyarranged winding-drum m, to which its otherend is connected. The winding-drum is loosely mounted on the loosesleeve ion the long stud pin or journal I), fixed on the lever b.

A worm-gear, f, is keyed on sleeve 2' and meshes with the worm c, thejournal of which turns in bearings 011 lever b, and is provided with afast ratchet-wheel, d. A pawl, l, piv oted to a fixed part of themachine, engages ratchet-wheel (I so as to turn it to the extent of onetooth at each depression of lover 1). Le-

the outer side of which a pair of graduated pawls, c e, are pivoted, oneor the other of which engages the ratchet-wheelie, so that thewinding-drum can turn only when the ratchetwheel 70 is turned by theworm gearing so as to ICO unwind the chain 9 step by step, antlthusprovide for the intermittent onward or building movementof the ring-railat the same time that the oscillations of lever I) provide for thetraverses or reciprocations of the ring-rail. After the chain g has beenunwound to the extent of allowing the ring-rail to be moved up to itshighest traverse the winding-drum is at once automatically reversed torewind the chain, and thereby return the ring-rail to the position oflowest traverse, in order that the completed cops or bobbins maybedotfed and fresh ones started. In reversing the winding-drum its pawls ee slip around the ratchet-wheel k. The reversal of the winding-drum iseffected by a shiftable pawl, 19, connected therewith and aratchet-wheel, a, which is mounted loosely on sleeve i, and isconstantly driven in a direction opposite to the step-by-step movementof the sleeve by a drive-chain, 2, driven by chainwheel 1 oncounter-shaft b and driving chainwheelo on the hub of ratchet-wheel n.Pawl p isat the proper moments thrown in gear with and disconnected fromthe ratchet-wheel n. It is yieldingly connected with the winding-drumtoprevent jerks in the mechanism. Thisyielding connection may be made invarious ways. As illustrated it consists of a rings, seated on aring-flange on the outer side of disk m of the winding-drum, which ringis connected by a spiral spring, 8, to the disk at, and carries the pawlp, which is pivoted to lugs thereon. Pawlp is offset so that its bitwill be in alignment with ratchet-wheel n. The tail of the pawl 12 isconnected with a lateral finger, p, which projects through a slot, 10 indisk at. The pawl moves with considerable friction on it's pivot, sothat it will notturn thereon of itself. A hook-headed stop-rod, q, is sosuspended from a fixed pendant, g, on the frame thatits hookhead will bein the path of the finger p of pawlp. During the unwinding of chain 9the pawl remains disengaged from ratchet-wheel it; but its finger pfinally catches on the hookhead of stop-rod q, and the pawl is therebyturned or rocked on its pivot, so as to throw it in gear withratchet-wheel a the moment the last layer has been laid on the cops orbobbins. Ratchet-wheel 01. immediately reverses the winding-drum, so asto rewind the, chain g and lower' the ring-rail. In order to disengagethe pawl 19 from the ratchet-wheel a the moment chain g has been rewoundto the required extent, a fixed projection, r, is formed on or attachedto lever I) to act on the finger p ofthe pawl, and turn it on its pivotso as to draw its bit out of the teeth of the ratchetwheel a. Thestop-rod g is adjustable 0n penddant .q, so that the point at which thereversal of the drum and rewinding of the chain is to commence can beaccurately regulated. It will be observed that the first effect of thedriving action of ratchet-wheel a on' pawl 19 will be to turn ring 8 inopposition to the stress of of springs, until finger p of the pawlreaches theend of slot 10 in disk m. After that the winding-drum iscompelled to turn with ratchetwhcel n. p the springs draws the ring 8back until the finger p of the pawl reaches the opposite end of slot 19Advantage is taken of these movements of ring 8 to operate a hook, it,carried by a spring, t, secured under the rim of disk m in a slot ofthesame, and applied for the purpose of lifting the latch 11 to release therod to with a notch, of which a pin, 1;, on the latch 12 is adapted toengage. Latch '0 is arranged to move up and down in suitable fixedguides, as shown, and has at its lower end a number of teeth on the edgefacing the rim of disk m, with which it is aligned. The hook t isarranged to play through a slot in the rim of disk at, so that when itis projected, as shown in Fig. 5, it is in position to catch on one ofthe teeth of latch con the reversal of the winding-drum. During theunwinding of chain 9 spring t holds hook tin the retracted positionshown in Fig. 3; but on the engagement of pawl 19 by ratchet-wheeln andthe partial turning of ring 8 the hook t is projected by a pin, a, onring 8 being forced under spring t, and

it is held projected thereby until pawl 11 is again disengaged fromratchet-wheel n and ring 8 drawn back by its spring 8. The hook t is soarranged on the disk at of the winding-drum that it will lift the latch'12 at the moment pawl p is disengaged from ratchetwheel a by theprojection r on lever 1).

Rod w, adapted to slide in suitable guides, is encircled by a spiralspring, to, between a cross-pin thereon and a fixed part of the frame.The spring is contracted when the notch of the rod is engaged by thelatch-pin 2), so that on its release therefrom the rod will be movedendwise by the resilience of the spring. This rod 10 is used forshifting the driving-belt of the machine from the fast pulley onto theloose pulley during its endwise movement by spring to, and thereby stopthe machine automatically the moment the ring-rail reaches its positionof lowest traverse after completion ofthe cops or bobbins. If the rod tois moved in the right direction by the spring w for shifting the beltfrom the fast to the loose pulley, the rod itself may be theshifter-rod; but if it should move in the wrong direction, as issupposed in this case, then it must be suitably the proper shifter-rod00.

On the disengagement of the pawl I Proper motion is transmitted from themain changes in the details of construction may be made withoutdeparting from the leading features of my invention.

It will be readily understood that in the operation of aspinning-machine provided with my reversinggear the ringrail is rapidlyreturned from the point of highest traverse to that of lowest traverse,and that by reason of this rapid descent an open spiral binding-threadwill be laid on the cops, and that, furthermore, the machine will beautomatically stopped at the proper time for doffing the cops.

Having thus described my invention, what I claim as new is 1. The.combination, substantially as before set forth, of the chain-drum, thecontinuouslyrevolving ratchet-wheel, the pawl connected with said drum,the adjustable stop for throwing the pawl in gear with theratchet-Wheel, and the oscillating lever supporting the drum andprovided with a projection for disengaging 20 the pawl from theratchet-wheel.

2. The combination, substantially as. before set forth, of thechain-drum, the ring, the spring connecting the ring to the drum, thepawl pivoted on the ring, and the continuouslyrevolw 25 JOHN F.VVORRALL.
